App1icaton filed October 11, 1912. YSerial No. 725,304.k

To all ro/0m t may concern.'

Bc it known that we, Riornnn) E. JoNEs and VICTOR ST. CLAIR MoN'rErrrI,residents of IIagerstown, in the county of l/Vashington and State ofMaryland, have invented a new and useful Improvement in Electromagnets,of which the following is a speciication.

This invention relates generally to registers and more particiiilarly toan electrically operated register particularly adapted for use inconnection with an ice chute for registering a number of cakes or blocksof ice entering the ice house or compartment, said ice chute forming thesubject matter of an application filed Aug. 26, 191:2, Serial Number713,612.

The register forming the subject matter of this invention is preferablylocated in the office of the ice house or cold storage plant, and isoperated by the opening and closing of the circuit accomplished by thepassage of a cake or block of ice through the ice chute.

The object of our'invention is to provide a register which will behighly efficient, quick in action and silent, and with these objects inview our invention consists in the novel features of construction,arrangement and combination of parts hereinafter fully described, andshown in the accompanying dra win In the drawings forming a part of thisspecilication, Figure l is a perspective view of a register constructedin accordance with our invention, the actuating mechanism being coveredand protected by means of a suitable casing. Fig. 2 is a detailperspective view of the register mechanism removed from the casing, andFig. 3 is a face view of the same.

In carrying out our invention we employ an ordinary mechanical counterA, having an ope 'ating arm A', at one end thereof. This counter isattached in any suitable manner to a strip B, of brass or other suitablematerial, said strip B, being connected to the forwardly extendingportion C, of the pole pieces C of the electromagnet, the core D being`surrounded by the requisite number of coils E of the wire, the terminalsthereofl extending into the circuit which contains a circuit closer theopening and closing of which serves to energize the elec tromagnet sothat the'armature plate F is drawn up to the vertical pole pieces C.

The armature plate Fis pivoted at G and the hanger plates II dependingfrom the rear end of the pole pieces C and projecting forwardly from thearmature plate F is the finger F to which is pivotally connected thelink I, which connects the finger F and the arm A of the register sothat at each upward movement of the armature plate the register arm willbe actuated to register one more number. The downward movement of thearmature plate is arrested by means of a hanger bracket K, thehorizontal member of which is faced with a cushion of rubber or othersuitable material K the purpose of this cushion being to prevent noiseand in order to prevent noise upon the upward stroke of the armatureplate we arrange a strip L from one pole piece to the other at the lowerforward end thereof, said strip L carrying a cushion strip L of rubberor other suitable material against which the armature plate strikes whenmoved upwardly and thereby preventing the same from coming into forcefulcontact with the pole piece and making a clicking noise.

It will be noted that the depending bracket K was offset so as not tointerfere with the free' and easy movement of the armature plate. Bymeans of a. mechanism herein shown anddescribed we are enabled toquickly and easily actuate the register at each closing of the circuitand the operations of the various parts both in closing and opening thecircuit are absolutely silent. The actuating mechanism heretoforereferred to is preferably contained withina metal casing M, having anopening M through which .the numbers of the register can be clearlyviewed. This case M 1s preferably constructed with supporting flanges M2by means of which it can be afflixed to the wall or other fixed object.

M3 indicates openings in the top of the case through which the wiresleading from the coil are adapted to pass.

A register constructed as herein shown and described has been foundcapable of fully carrying out all the objects herebefore referred to.

What we claim is:

An electromagnet comprising a core,l reetangular pole pieces at the coreends, a cross strip Connecting said cores, an armature plate hinged atits rear side to said cores, u hunger bracket Carried by the front ofone pole piece and acting as a stop to downward movement of the armatureplate, a. cushion on said bracket, L strip carried by the front edges ofthe pole pieces, and n cushion on said strip, said cushion :loting as a.stop for upward movement of the armature, as and l0 for the purpose setforth.
